Good morning,
I have to fetch about 100 items from the datastore and I considered
doing it this way:
select from ... where x == 5 || x== 9 || x==30 || x==2 || x==0 ||

In the end it wasn't hard to roll my own system which simply uses

The site looks alright but a couple of things:
- Using the marquee tag usually leads to being banned from the Internet.
